Combustion LES requires modelling of physics beyond the flow-field only. These additional models lead to further quality issues and an even stronger need to quantify simulation and modelling errors. We illustrate stability problems, the need for consistent modelling in premixed and non-premixed combustion, and show how RANS models that have frequently been applied in an LES context can lead to strong conceptual errors. We outline the application of the error landscape approach to a complex non-premixed flame, and investigate several error indicators that have been developed for situations where no experimental reference data is available.
